For a substance that has only been used widely for six decades, guar gum is extremely popular. After the Second World War, when industries in the West faced a shortfall of locust bean gum, which was at that time used widely in the textile and paper industries, guar gum was introduced as an alternative. The technology to extract guar gum from the guar plant was developed around that time as well and was made available commercially in 1953. Since then, guar gum has been used extensively in the manufacturing and production sector all around the world.
So, you may be curious where this substance is produced and more importantly, how it is produced. The guar bean is grown primarily in the US, India, Australia, and Pakistan, in addition to some parts of Africa. India is the largest producer of guar, with around 3 million tons produced annually, followed by Pakistan at 0.25 million tons. From there, the guar is transported to facilities for converting into guar gum. Again, India is a major producer of guar gum followed by the US. The substance is then shipped around the world, wherever needed, as it is used in a number of industries.
The extraction technique for the gum depends on the purpose for which the guar gum will be used. For instance, the most widely used technique involves several steps, including roasting, polishing, and also sieving. On the other hand, guar gum used in the food industry is manufactured over a number of stages, as it has to be safe for consumption by the end user. All in all, the techniques vary based on the purpose for which the guar gum will eventually be used.
So, you now have a clear idea of how guar gum is produced and from which regions it is shipped around the globe.
